Improvement in manufacturing nuts, bolts



UNITED STATES PATENT OFFICEo JOHN MARSDEN, OF ORRELL, ENGLAND.

IMPROVEMENT IN MANUFACTURING NUTS, BOLTS, &C.

Specification forming part of Letters Patent No. 38,116, dated April 7, 1863.

T0 all whom 'tmay concern:

Be it known that I, JOHN MAnsDEN, of Orrell, in the county of Lancaster, England, screw-bolt manufacturer, have invented Improved Machinery or Apparatus for Making, Forging, and Punching Metal Nuts, Bolts, Spikes, or Washers and I hereby declare the following isa fulland exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature ot' my invention consists in making nuts of round rod or bar iron (or other metal) without waste and ready for tapping as the fully-formed nut drops from the machinery.

To enable others skilled in the manufacture to make and use my invention, I will proceed to describe its construction and operation.

In the drawings, Figure 1 is a top plan of the entire machine, showing the principal working parts; Fig. 2, a front view of the disk-wheel detached; Fig. 3, front view of openin g and closing die and its appurtenances, and Fig. 4, longitudinal and vertical section of the ram and parallel punch.

Similar letters of reference denote corresponding parts at each of the gures.

Upon a framing denoted by the letters a a are mounted suitable gear-wheels and shafts (the which being represented in the drawings at Fig. l need no further description) for the purpose of obtaining and communicating the power required to work the machine. A diskwheel, b, is employed, having teeth around its periphery, and upon the plane or side of this disk-wheel are placed two or more sets of in clined planes, three only being shown in the drawings. The one set, c, works a hollow ram, the other set, d, which are made movable, are capable ot' being adjusted according to the substance of metal the nut or washer is to contain, working a parallel punch, y', (which is shown more fully at Fig. 2.) A dat cylinder, d', is attached to the disk-wheel, forming boss, upon which are other sets of inclined or curvilinear planes, the first set, e, drawing back the hollow ram after it has performed its work, the second set, If, also curvilinear, drawing back the parallel punch. The hollow ram g is inserted in a space in a block or cylinder, h, attached to the frame a, and slides horizontally therein. In front and immediately opposite the end ofthe hollow ram gis a die, i, in two halves, of the size and shape of the nut to be made and hinged or jointed by a leg, j, Fig. 3, similar to a vise-leg. This die is opened by means of a weight, lc, and closed, when required, by the triangular cam l, or if four sets of inclined planes are used then a quadrangular cam is to be used, and so on according to the number of inclines and size of the wheel. On the outside of the die t' and on the upper part of the frame a is a sliding vise, m, Fig. l, which holds the rod of iron while the nut is being made and is actuated by another similar cam, u, which is drawn back to release the rod by a rope or cha-in having a weight suspended to its lower end. Jaws of sizes suitable to the different diameters of iron used are screwed into the vise m. O denotes a stud ou the end of ram p similar to stud on the end of the parallel punch.

The working of the machine is as follows: The bar or rod of heated iron i* is passed through or into'the vice m, and pushed further or into the center opening in the nut die i, (shown at Fig. 3,) by which time the cam u has closed the vice and gripped the rod lirmly, the cam l having closed the die simultaneously. The hollow ram g is now forced forward onto the end of the bar or rod within the die by the force of the inclined planes c abutting against its heel or back end. 'Ihe hot iron being now pressed into the die and formed externally into a nut, the parallel punch g is pressed forward by the inclined plane d passing between the forked en of the hollow ram, before which the vice m is opened and the bar released, the piece pressed or punched out of the center of the nut i-emaining on the end and leaving the bar entire, except as to the portion which has been made, by the operation of the ram within the die, into a nut. The incline con the cylinder d now comes into contact with a projecting pin or stud, o, Fig. l, on the end of the hollow ram g, which draws it back to its starting-point, when the second incline, f, comes also in contact with a pin or stud, p, Fig. 4, on the end ofthe parallel punch g', which either draws out the nut with it in retiring or allows it to fall from the die i into a receptacle beneath.

When this machine is used for making washers, no alteration is necessary except taken off'. y

What I claim as of my invention,`and desire to secure by Letters Patent, is-

1. The making, forging, and punching nuts and Washers, without waste of metal, from round rod or bar iron or other metal, by the combination of mechanical parts put together and Working essentially as hereinbefore de scribed and shown.

2. The making ol' bolts or spikes by and withvthe combination of mechanical parts, (the modifications herein directed being previously made,) put together and Working essentially as hereinbefore described.
